To all 'whom 'tt may concern.:

Be it -known that I, Persi; BROWN, a citileen of the United States, residing'at Troy, -in the county of Latah and Stat-e of Idaho,

have invented certain `newland, useful Improvements in Condensers, of which the. .tollowing is a speciication, reference beingdrawings.

had therein tothe. accompanying This iiiventioii'relates tocondensers and,

more particularly, to that class which are used in connection 4with retorts employed,

.- of the members, emp

'lhe object of the invention is the pro,- vision of apparatus of' this nature wherein'l the lvaporous distillate is not only acted upon by acooling agent to` cause the vaporous portions thereof to bedisassociated from the permanent..gases but likewise enables the former, or liquefied, products to be 'withdrawn in the shape 'ofy various liuids, suoli as turpentine, tar-oil, etc.

With these andfother objects in view, the

invention Vconsists, in the novel construction Vand adaptation of devices, as will lbe hereinh after described and claimed.

In the accompanying drawings, Figure lis a longitudinal elevation Vof a condenser embodying my invention but with the containing ease in section; Fig. 2 is a transverse section' of the saine taken through 242 of' 1. Fig. 3 .is a-fragnientary longitudinal vertical section ofv the. apparatus. Fig. 4 is a erspective View of `one cooling receptacles.

The reference numeral 5 ldesignates the outer shell and 6 the inner shell ofthe condenser-easing and are each made watertight and of such relative sizes as to-provide a space '2'V4 for water therebetween.` Within the .shell 6 are a series of water-tight recep-v tacles 8 of a width to make a nice lit between the side walls of lthis shell, but of4 lengths so aste urnishspacest) and 9 between their l, opposite ends and the adjacent end wallsA of the shell. lThese closed pans .are each made with its top 8 benttoslopedown wardly from the opposite sides'to a niedial.A

plane and afford a' gutter whereunto the condensations which ma cipitated thereupon wi flow toward the longitudinal axes of the respective pans'.

The pans are `furthermore inclined so that the eondensations will also' flow towards their lowerends, and which, for convenienee, are arranged to be alternatelymt the Specification of Letters Patent.

opposite ends, that is to say, the lower 'end of the lower Span will be at one endof the casing, that. of the next above-at the opposite end, and soon. The lowermost pan is lconnected by a pipe 10 with a source of unter-supply -and each pan communicates at its upper end with the lower end ofthe pan next above by tubes 11, while from the of the top pan is a discharge pipe-19'. ,4 ,Y rl`he space 7 intermediate the casing shells may be.' charged with water in anyfsuitable way, as by branches 10 and 12 of the afore- T he pans arenetained in their inclined relative positions by means of supports, such i as.V bracket pieces 13 secured to the inner shell to bear the lower pan Aand transversely disposed bridge members 14: interposed between thepans. These members are desir- `ably formed with two legs toaii'ord stability, and are formed to have their edges titwith the' juxtaposed pans and also with .theside walls vot' the inner shell. Alongthe lower edges of these members they are provided with notches 14 and 14, which are respectively located centrally of the width of the pans and to each side thereof.

At the lower end of each of the pans and closing the space 9 between the same and the adjacent wall of the shell 6 is a ledge 15 having at its midrlength a depression, orreceptacle, 15* whereinto flow the `condensations from the -pan supported by the ledge.

`1G are pipes extending into said receptacles for draining the liquids which collect therein, but to prevent an. accompaniment ofthe,l

n and l2 and respectively ex# tending through the 4outer shell of the eas .ingator .near the top and bottom.

gases with the liquid each of these pipes is `provided with a downwardly directed U- shaped bend 16 where `the liquid collects to form a seal. e y d l Extending through the casing shells and at some distance from-the bottom is a pipe 1T which` is bent at 17 toi'urnish a seal, to

prl'ent the escape of gases y therethrough with the heavier ,oils which wouldbe drawn from the condenser through the pipe.

bowls 18 which are each provided with a dependingpipe 19 which passes through'the ,easing andisprovided with a cap or other ldetachable closure. Protruding into each of these bowls is the end of a pipe 2() which leads from the retort to convey the gases vUpon the bottoni ofthe casing-shell 6,-are I therefrom into the condenser. 21 are tubes leading from the outside of the casing and terminating above said bowls so that the latter may be charged with a liquid to subinerge the lower ends of the pipes 2O and .seal them against the return iiow of the gases when they have escaped into the condenser.

I illustrate in Fig. 2 a funnel 21 attached to one of these tubes into which the liquid may be conveniently :poured for illing the respective bowl, bu't .anyother means may be used instead. 22 represents a pipe leading from the top of the condenser whence the permanent, or residual, gases are conducted to a gasoineter or to a service pipe.

The operation of this invention may be de- .'scribed as follows: The volatile products of the distilling apparatus, with which this invention eoperates, discharge into the conof this pan and thence passes between the lower two pans to the opposite end of the.

condenser where it enters through the next space 9 to between the second and third pans and so ascendingA successively in reverse dir'ections, with recurrent removals of the liquefiable portions by encountering the successive pans in its course to the gas delivery pipe 22. The iow of the gas is obstructed by the members 14 and by which the gas can only pass through the notches 14 or 14 of the same, and by so doing the gas is longer subjected to the condensing action of the pans within the various compartnients. The liquid thus obtained will be collected upon the tops of the pans from which it flows int-o the respective receptacles whence it may be drawn off through the trap-pipes 16. .The nature of the liquids deposited. upon the various pans differs, and

l is of unequal commercial value, consequently by thus providing means to separate the saine the usefulness of the condenser is increased. v

The purpose of the bowls 18 is to provide means to entrap sedimentary matter which may accompany the gases as they enter the condenser, and this matter is removed from time to time through the. connecting pipes 19. Some sediment will also collect in the pipes 20, and for this reason, the latter should be so arranged at a point outside the condenser as to a ord means for introducing a scraper or brush to clean the interior of these ipes.

The advantages of the invention reside in the adaptation of the various parts of the apparatus whereby distillate gases are not only separated through a process of condensation, but such function is accomplished 'in such manner as to readily save the .com-

ponent oils, oi acids, without becoming cominingled. y
